WILLIAM H. REIFE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- THIRD 'IO ANDREW M. SEIP, JR., OB SAME PLAGE.

ELECTRlC -WIRE INSULATOR.

SPEGIFICATION forming pa.rt of Letters Patent N0. 274,821, dated March 27, 1883.

Application filed February 7, 1883. (l\'o mudel.)

T all whom z't mag; ooncern:

Be it known that I, WILLIAM H. REIFE, 0f

the city of Philadelphia, count v of Philadelphia, and State of'Pennsylvania-, have invented an Improvement in Electrie-VVire Insulators, of which the following is a. speeification.

My invention Das reference t0 insulators for electric ivires; and itconsistsin an inverted-cup glass casting, in which is secured, at the t0p, a metullic hook, linder whieh the wire is piaced, the said hook being placed at a lowerlevel than the supporting-rims 01' glass, and in many details of constructiou, all 0f which are fully set fonh in the following specification, and shown in the accompanying drztwings, which form part thereof.

lhe object 0f my invention is t0 provide a suitable and cheap device t0 insulate wires generally, but more partieularly th0se supported upon telegraph:poles.

In the drawings, Figure lis a seelional elevation 0f my improved insulator 011 line 00 x. Fig. 2 is a plan view of same, und Fig. 3 is a perspective view of the metailic hook cast in the glaSs.

A is the glass body, und is provided with a slightly-conical hole, B, to fit upon the support of wood; 01, if desired, this hole may be screwthreaded, as is customary. The t0p part is de pressed 01 saucer-suaped, as at O, and in the middle is east the hook D, having at the bottom the retaining enlargement D, and at the top the hook d, having the opening d, opening therein close to the bottom. Any other i'orm of hook mny be used, as I d0 not limit myself t0 the partieular construction shown. [t is not desirable that the bottom D 0f the 11001;- piece should extend into the socket B,though such a construetion is possible.

O is a rirn on theupper edge of the body A, and is somewhat above the top 0f the hook, so that the wire G must be bent down t0 be placed under the hook part d, and is prevented from sliding by grooves E, in which it rests.

Part 0f this rim G may be cut away, as at F, 5

tend all aronnd, unless desired, as simple grooved extensions may be used, 0ver wbich the wires are guided.

The greate1 tue weight 0n tlle wi re the stronger it holds upon the insnlator; bu t if it should break, in platze 0f putting; all the stmin 0n 0ne side, the wire wonld slip off und the end fall t0 the ground 0r draw through the hook until supported, so as t0 relieve the p0ie from any excessive unbalanced strain.

I do n0t confine m yself t0 the exuct f'orm shown, as it may be modified in various wztys without departing fr0m my invention.

Having now deseribed my invention, wlmt I claim as new, und desire (0 secure by Letters Patent, is

l. An insniator f0r electriewires, which cousists of a body 0f insulnting substance, provided 0n the top with an inverted hook, and extensions over whieh the wire is piaced, Etlld by Which it is held fast in seid 110011, substantially as and for the purpose specified.

2. The combination 0f body A, having 1'in1 o1 extensions E,andinvertedl100kpieceD,cast in the top of seid body, substantiztlly as und for the purpose speeified.

3. 'lhe combination 0f body A, havingsaucer-shaped top, with outlet F, and inverted hook-pieee D, esst in alle top 0f said body, substantially as atnd for the purpose specified.

4. 'Ihe body A, having depressed 01 saucershaped t0p O and rin1 E, in combinntion with inverted hook-piece D and wire G, substantially as und for the purpose speci'ed.

In testimony 0t' which invention I hereunto set my band.

WILLIAM H. REIFE.
